Abstract

The present invention is an airtight case comprising a base for receiving a stick-type product, a hollow cap, and a hollow plug sleeve inserted within the cap. The plug sleeve has an open end and a closed end, the closed end being a flexible bellows. This case is useful in reducing the adverse effects caused by the pressure build-up associated with sealing or airtight cases. When the cap of the present invention is placed on the base of the case the bellows expands in response to the compressing of the air located within the inner chamber of the case, thus preventing the cap from being pulled away from the base. Also, when the cap is removed, the bellows contracts and prevents the product from being pulled out of the base.

Description

The airtight cosmetic case that has bellows
Technical field
The present invention relates to a kind of sealing of viscous product or airtight box body of being used for, when lid when box body covers or opens, this box body can help to discharge the inner pressure that forms.
Background technology
Owing to need to produce the viscous product that contains volatile solvent, because viscous product is when being coated on the skin, volatile solvent guarantees that product has good " sensation ", and volatile solvent makes product become dry rapidly, adhere to.Be because the volatilization of product with the afoul problem of the type of these compositions, the volatile solvent in the component is easy to lose.
The minimizing of the volatile solvent of opposite viscous product influences the physical characteristic of product, and reduces the volatile materials delivery quantity.Even when storing under the temperature that is being lower than room temperature, it has been observed that volatile solvent is reducing always.
The case of prior art provides a kind of sealing box body (seeing United States Patent (USP) 5197814 and 5342134) of remedying this problem, and this case is provided with in the lid of a coiled casing insertion box body.When lid was placed on the base of box body, coiled casing contacted with the outer wall of base, and has sealed box body effectively, to prevent volatilization loss.As described in the present invention, sleeve pipe flexible is in order to form sealant between Bottom of box body and lid, thereby sleeve pipe is centered around any minim gap on the susceptor surface and deflection and formed a sealant.
Although this box body forms a sealant effectively between internal chamber and external environment condition, problem is to stand the inner pressure that produces.The inner pressure that produces is when closing the lid, and the compressed air in the box body produces.
The compression of air has produced many unappealing product results in the box body.At first, when closing the lid, the air compression causes back-pressure, and it promotes lid makes it away from base.This produces the gap between lid and base, this gap does not have aesthstic attractive force and it the sealing validity variation between making base and covering.In order to eliminate this problem, can improve, as the inside diameter that reduces lid between the lid and bottom seat, to form air-tight fit.It is more difficult that same this also makes lid open from base, and this is that the consumer is unacceptable.
The tight fit of lid has solved back-pressure makes the problem of lid away from base, but needs when covering other shortcoming to have occurred the bigger power except that taking off.When lid installs, the pressure that the inside in the box body internal chamber produces will dissipate lentamente by micropore, and reach balance with external environment condition.This can not take place at once.Box body will be filled, and be stored in the warehouse, transport to sales counter then, allow the consumer buy.The dissipation of internal pressure will take place in interior pressure is full of time of box body some months to consumer's hand always.
When internal pressure equates with external environment condition pressure, take off lid and cause the internal chamber pressure drop.Produce swabbing action, on the contents of product surface and box body " absorption ".This suction will make product take out from clamper, or fracture, thereby the consumer can not use this product.
Summary of the invention
The invention provides a kind of box body that contains the viscous product of volatile solvent, it can help to prevent that volatile solvent from losing from viscous product.
The present invention also provides a kind of box body that can help to prevent the ill effect relevant with the pressure dissipation in inner pressure that produces and the sealing box body.
The present invention provides a kind of box body that contains the viscous product of volatile solvent again, and wherein most of parts of existing standard box body still can adopt, thereby reduces the cost of change wrapping tool.
In addition, the box body that contains the viscous product of volatile solvent provided by the invention loses from viscous product to have prevented volatile solvent, and adopts simple relatively equipment simultaneously, and has avoided impairing the packing aesthetic feeling.
The present invention proposes a kind of airtight cosmetic container, comprising: a base of laying viscous product; A hollow cover that has inner and outer wall; A hollow pipe close that inserts in the lid, this pipe close comprises an openend and a closing end, the openend of described openend and lid is positioned at the same side, this pipe close is made by one section flexible bellows in described closing end one side, when this flexible bellows is in normal condition, one segment distance is arranged at the top of its top and lid, when closing the lid, the inwall and the base Elastic Contact of openend one side of described pipe close, form sealant, along with the sealing of box body, thereby the air in the box body is compressed and makes described flexible bellows elongation, when taking off when covering, the reducing of the air pressure in the box body will make described flexible bellows shorten; On the inwall of the outer wall of hollow pipe close and/or described hollow cover, one or more longitudinal furrow grooves are set also, the length of groove is enough to extend to from bellows the openend of pipe close, be used to guarantee to cover with pipe close between air communicate with external environment, thereby can not influence the flexible of flexible bellows.
This box body is used to reduce the reaction that causes with sealing or the caused inner pressure that produces of airtight box body.When lid of the present invention was buckled on the base of box body, bellows was with the compression elongation of the air in the internal chamber of box body, prevented that like this lid from deviating from from base.Equally, when lid takes off, bellows compression and prevent that product from pulling out from base.
